由于项目需要，需要在kali上添加一条路由，并且保证重启后仍然生效。
经查找发现有两种可行的方法：
1、修改/etc/network/interfaces配置文件，添加一行，如：
up route add -net 10.105.10.0 netmask 255.255.255.255 gw 192.168.1.1 eth0
-net指这是一条网络路由（ip地址主机位为0）
gw指下一跳
2、修改rc.local，添加：
route add -net 192.168.114.0/24 dev eth0
或
route add -net 192.168.114.0/24 gw 192.168.3.254
那么，为了保证重启仍然生效需要将它写入rc.local配置文件。
--------------------------------------------分割线--------------------------------------------------------
第一个方法添加路由后，使用route命令查看路由表；的确是添加了，但实际测试中发现没有起作用，目标仍然不可访问。（玄学问题）
第二个方法遇到一个问题，kali把rc.local“ 服务化”了，并没有rc.local配置文件怎么办呢？
解决方法：
vim /etc/systemd/system/rc-local.service
将内容替换为
[Unit] Description=/etc/rc.local Compatibility ConditionPathExists=/etc/rc.local [Service] Type=forking ExecStart=/etc/rc.local start TimeoutSec=0 StandardOutput=tty RemainAfterExit=yes SysVStartPriority=99 [Install] WantedBy=multi-user.target
然后
touch /etc/rc.local（正常情况下/etc/rc.local并不是配置文件本身，而是/etc/rc.d/rc.local的软连接；但徒增麻烦不建议那么做）
记得赋予执行权限
chmod +x /etc/rc.local
vim /etc/rc.local
添加
#!/bin/bash # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES # # It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this file. # # In contrast to previous versions due to parallel execution during boot # this script will NOT be run after all other services. # # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure # that this script will be executed during boot. exit 0
插入脚本就在exit 0之前即可
重启rc-local服务
systemctl restart rc-local.service
设置开机自启动
systemctl enable rc-local
---------------------------------------你以为这样就结束了？-------------------------------------------
我将添加路由的shell命令添加到rc.local之后重启发现，并没有成功添加路由；
执行systemctl status rc-local.service发现报错显示“网络未启动”。。。。
在检查了各种错误之后我断定，是启动优先级没有起作用
无奈曲线解决，在启动脚本里添加sleep命令延迟执行脚本
详见我的shell脚本：
#!/bin/bash # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES # # It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this file. # # In contrast to previous versions due to parallel execution during boot # this script will NOT be run after all other services. # # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure # that this script will be executed during boot. /usr/local/bin/route-eth0 exit 0
/usr/local/bin/route-eth0:
#!/bin/bash sleep 15s route add -net 192.168.114.0/24 dev eth0 exit0
最终问题解决，目的是给更多人带来方便。
